[0027] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A functional filter for a hair dryer according to an embodiment of the present invention will be described below with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments.

[0028] (Embodiment 1) The functional filter for a hair dryer according to this embodiment is attached to the air outlet of a hair dryer. Specifically, as shown in Fig. 1, the functional filter for a hair dryer 1 according to this embodiment has a structure in which a lattice-shaped member 12 is fitted into an annular member 11, and a plurality of spaces 15 are formed by the lattice-shaped member 12.

[0029] The functional filter for hair dryers 1 has a plurality of spaces 15, which provides a large surface area that can come into contact with the hot air blown from the hair dryer, and can radiate high-intensity electromagnetic waves by thermal radiation and rectify the hot air blown from the hair dryer in a predetermined direction. In addition, the functional filter for hair dryers 1 has sufficient strength.

[0030] Next, the material constituting the functional filter 1 for a hair dryer will be described. The material constituting the functional filter 1 for a hair dryer is a material containing 15 to 45% by weight of Fe. 2 O 3 (iron dioxide), 10 to 33% by weight of SiO 2 (silicon dioxide) and 13 to 45% by weight of Fuji lava produced in Fujinomiya City, Shizuoka Prefecture (hereinafter referred to as "Fuji lava").

[0031] Here, Fuji lava refers to Fuji lava mined in Fujinomiya City, Shizuoka Prefecture, which is the same as or recognized as having the same composition as shown in Figure 2, or rock recognized as the same in the industry that handles rock as a ceramic material. Note that if the concentration of each material is lower than the above-mentioned concentration range, the effects on hair described below cannot be fully exerted, and if the concentration is higher than the above-mentioned range, the quality (color, strength, etc.) of the functional filter for hair dryers will decrease and the production yield will become unstable.

[0032] Other materials contained in the functional filter 1 for a hair dryer are not particularly limited, but include Fe, 2 O 3 , SiO 2It is preferable that the material does not absorb much of the electromagnetic waves (radiated at 35 to 110°C) emitted by the thermal radiation (thermal radiation) from the Fuji lava. Other materials that can be included include cordierite (magnesium oxide (MgO), aluminum oxide (Al 2 O 3 ), silicon dioxide (SiO 2 ), tourmaline, germanium, radium, etc. The functional filter 1 for a hair dryer containing cordierite as another material not only has a high effect on hair as described below, but also has low thermal expansion, high thermal shock resistance, and high mechanical strength.

[0033] The functional filter 1 for a hair dryer can be manufactured using the same manufacturing method as that for general ceramics.

[0034] Next, we will explain the effects of blowing air at 35 to 110°C onto human hair using the functional hair dryer filter 1 made from each material. The details of the mechanism of the effects described below are currently unknown, but it is thought that they may be due to the thermal radiation of each material.

[0035] First, the material is 15 to 45 wt % Fe 2 O 3 The case where the functional filter 1 for a hair dryer containing the above-mentioned ingredients is used will be described. The functional filter 1 for a hair dryer is attached to the air outlet of a hair dryer, and air at 35 to 110°C (air volume 0.3 m) is blown from the hair dryer onto human hair. 3 / min~2.0m 3 / min.), compared to when air of the same temperature is blown onto human hair from a conventional hair dryer, the hair becomes moist, calm, shiny, soft, fine and smooth to the touch, and the hair is less frizzy and more manageable.

[0036] The material contains 20 to 45% by weight of Fe. 2 O 3The functional filter 1 for a hair dryer preferably contains 35 to 40% by weight of Fe, and particularly preferably 35 to 40% by weight of Fe. By using such a functional filter 1 for a hair dryer, the above-mentioned effects can be further improved. 2 O 3 When the functional filter 1 for a hair dryer containing SiO 2 In comparison with the functional filter 1 for hair dryers containing Fuji lava, the smoothness is less, and the volume is not increased compared with the case where the functional filter 1 for hair dryers containing Fuji lava is used.

[0037] Next, 10 to 33% by weight of SiO 2 The following describes the use of a functional filter 1 for a hair dryer containing the above-mentioned compound. When this functional filter 1 for a hair dryer is attached to the air outlet of a hair dryer and air at 35 to 110°C is blown from the hair dryer onto human hair, the hair feels smooth (smooth), shiny, and light, and the curls of the hair are straightened (the degree to which curls are straightened), making it easier to run your fingers through, and leaving it smoother, compared to when air at the same temperature is blown onto human hair from a conventional hair dryer.

[0038] The material is 15 to 33% by weight of SiO 2 The functional filter 1 for a hair dryer preferably contains SiO 2 , and more preferably contains 20 to 25% by weight. The use of such a functional filter 1 for a hair dryer can further improve the above-mentioned effects. 2 When the functional filter 1 for a hair dryer containing Fe 2 O 3 The moist feeling is less than that of the functional filter for hair dryers 1 containing Fuji lava, and the volume is not increased compared to the case where the functional filter for hair dryers 1 containing Fuji lava is used.

[0039] Next, we will explain the use of a functional hair dryer filter 1 containing 13 to 45% by weight of Fuji lava as a material. When this functional hair dryer filter 1 is attached to the air outlet of a hair dryer and air at 35 to 110°C is blown from the hair dryer onto human hair, the roots of the hair become fluffier, the overall volume of the hair increases, and the hair becomes more resilient, shiny, and fluffy, compared to when air at the same temperature is blown onto human hair from a conventional hair dryer.

[0040] The functional filter 1 for hair dryers preferably contains 20 to 45% by weight of Fuji lava, and more preferably 30 to 40% by weight. The use of such a functional filter 1 for hair dryers can further improve the above-mentioned effects. However, the functional filter 1 for hair dryers containing Fuji lava contains Fe. 2 O 3 The moist feeling is less than that of the functional filter 1 for hair dryers containing SiO 2 It has less of a smooth feeling compared to Functional Filter 1 for Hair Dryers, which contains

[0041] Here, the temperature of the air blown from the hair dryer is preferably 60 to 110° C., and particularly preferably 65 to 100° C. By setting the temperature of the air blown from the hair dryer within this range, the above-mentioned effects can be further improved.

[0042] Furthermore, the above-mentioned effects can be obtained by blowing air at 35 to 110°C onto human hair once (for example, for 5 minutes) using the functional filter 1 for a hair dryer made of each material, but even greater effects can be obtained by repeatedly blowing the same action multiple times.

[0043] Each functional filter for a hair dryer shown in Figure 3 was manufactured, and an experiment was conducted on the same person to dry their hair under the following conditions: 1. After washing, the hair was removed with a towel. 2. The same hair dryer was used under the same conditions (air temperature at the outlet: 80°C, air volume: 1.6 m 3 / min) <Comparative Example>

[0044] An experiment of drying hair was carried out under the same conditions as in Examples 1 to 3, except that the functional filter for a hair dryer was not attached to the hair dryer.

[0045] Photographs of the experimental results are shown in Figures 4 to 7. Figure 4 shows the experimental results when filter A was used, Figure 5 shows the experimental results when filter B was used, Figure 6 shows the experimental results when filter C was used, and Figure 7 shows the experimental results of a comparative example.

[0046] As can be seen from the experimental results, Fe 2 O 3 In the example using filter A containing , compared to the comparative example, it was found that hair became moist, calm, shiny, soft, fine and smooth to the touch, the frizz of hair was reduced, and the hair became more manageable. It was also found that this effect was greater when used continuously for one week (once a day for 7 days) than when used once.

[0047] Next, SiO 2 In the example using filter B containing Fe, it was found that the hair felt smooth, shiny, and light, the curls were straightened (stretching degree of curls), and the hair was smooth and easy to run your fingers through, compared to the comparative example. 2 O 3 It was also found that the moist feeling was less than that of Functional Hair Dryer Filter 1, which contained 1. Furthermore, it was found that this effect was greater when used continuously for one week (once a day for seven days) than when used just once.

[0048] Furthermore, in the example using filter C containing Fuji lava, it was found that compared to the comparative example, the roots of the hair became fluffy, the overall volume of the hair increased, the hair became stronger, and the hair became shiny and fluffy. 2 O 3 The moist feeling is less than that of functional hair dryer filter 1 containing SiO 2The dry feeling is less than that of the functional filter 1 for hair dryers containing . Furthermore, it was found that this effect is greater when used continuously for one week (once a day for seven days) than when used just once.

[0049] Next, in order to confirm whether the effects of each of the above-mentioned filters are generalizable, an experiment was conducted in which people with certain attributes had their hair dried under the same conditions as in the above-mentioned examples. After that, the people who underwent the experiment were given a questionnaire shown in Figure 8.

[0050] Figure 9 shows the attributes of the subjects in the experiment using Filter A and the results of the questionnaire, and Figure 10 shows the statistical data. As is clear from these results, many subjects felt the same effect from Filter A as in the experiment described above. Note that, because this test was a sensory test (sensory evaluation), it is likely that low ratings were included due to differences in perception among individuals (the same applies to the evaluation results for Filter B and Filter C).

[0051] 11 shows the attributes of the people who were subjects of the experiment using filter B and the results of the questionnaire, and Fig. 12 shows the statistical data. As is clear from these results, many people felt the same effect as in the above-mentioned experiment with filter B.

[0052] Furthermore, Fig. 13 shows the attributes of the people who were subjects of the experiment using filter C and the results of the questionnaire, and Fig. 14 shows the statistical data. As is clear from these results, it was found that many people felt the same effect as in the above-mentioned experiment with filter C. (Other Embodiments)

[0053] In the above-described embodiment, the shape of the space when viewed from the air outlet side is square, but the present invention is not limited to this. The shape of the space when viewed from the air outlet side may be, for example, rectangular, diamond-shaped, fan-shaped, honeycomb-shaped, or the like.
